Title: Improvements in or relating to wet screening and filtering apparatus
IPC: B03B5/56
Filed: 1958-10-06
Abstract: 921,012. Filters. T. W. McNEILL. Jan 6, 1960 [Oct.. 6, 1958], No. 31760/58. Class 46. The screening surface of a vertical inclined or, as shown, horizontal centrifuge, which may be cylindrical or frusto-conical is composed of e.g. lengths of wires 13 of triangular or wedgeshaped cross-section, and ribs 14 which stand proud of the surface and form a plurality of pockets 15 at least adjacent the end of the intake duct 16. The ribs 14 are secured in position by rods 18 which are passed through loops 13a of the wires 13 to secure the same together. A multi-bladed stationary plough 17 is provided for continuous excavation of the solids, or this may be effected by imparting a vibrating or oscillating motion to the screening surface where this is frustoconical, The wires 13 adjacent the outlet end of the duct 16 may be of relatively heavier gauge. The wires 13 may alternatively be secured together by welding to support bars and the screening surface shape may be formed by joining a number of segmental areas of wires 13, bounded by metal frames, together. The screening surface may be formed from perforated plate, woven or crimped wire instead of the wires 13. The Provisional Specification describes various other constructions of cylindrical filters composed wholly or in part of wedge wire screening surfaces. One construction has a plurality of possibly contra-rotating concentric cylinders, and another a cylinder through which liquid passes from the outside to the inside.

Title: Method of Making Contact to Semiconductor Components and Solid-state Circuits
IPC: H01L23/48
Filed: 1966-07-15
Abstract: 1,159,393. Semi-conductor devices. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 15 July, 1966 [17 July. 1965], No. 31822/66. Heading H1K. A semi-conductor structure is mounted on a housing base comprising a glass or ceramic substrate bearing terminal regions from which extend conductive areas or tracks. " Conductive " semi-conductor regions 11 insulated from other semi-conductor regions 7 containing active (and, possibly, passive) devices extend between the upper and lower faces of the structure. The " conductive " region may be paralleled by a thin metallic layer to obtain increased conductivity. The upper face of the structure is covered with a insulating layer over which extend deposited metallic strips 2 interconnecting electrode regions of the devices with respective " conductive " semi-conductor regions. The structure is bonded to the substrate by simultaneous soldering of the lower faces of the " conductive " regions 11 to conductive areas 15, 16 on the substrate; optionally the bulk material of the device-containing regions or polycrystalline material deposited therebelow may be soldered to a track during the process. Devices may be formed in separate semi-conductor regions derived from an initial monocrystalline body consisting of an epitaxial layer on a relatively low resistivity substrate. These regions are isolated by insulation 5 from " conductive " regions formed by the deposition of polycrystalline semi-conductor into holes dividing the original monocrystal. The separate regions are held prior to the deposition by an insulating layer produced on the opposite surface of the original body; this layer may be reinforced by a temporary layer of polycrystalline semi-conductor. Constructions are described (such as oxidized grooves 20, 19) which minimize the spread of solder between adjacent bonding areas when the structure is bonded to its base. Devices formed in the separate regions may be transistors or switching circuits. Many of these may be formed from one starting body and divided therefrom after the provision of the insulated " conductive " regions.

Title: Improvements in or relating to control valves for liquid pressure braking systems
Inventor: OSBORNE DUNCAN WILLIAM
IPC: B60T13/12
Filed: 1968-07-04
Abstract: 1,221,544. Valves. AUTOMOTIVE PRODUCTS CO. Ltd. 18 June, 1969 [4 July, 1968], No. 31852/68. Headings F2F and F2V. The valve is for connecting two separate hydraulic pressure inlets (26), Fig. 2 (not shown), each to a separate motor port (27) and selectively connecting the motor ports to an exhaust port 25. It is applicable particularly to vehicle brake systems in which separate sets of brakes are to be operated from individual sources. The valve comprises two plunger valve members 28 in parallel bores joined at one end by the common exhaust chamber 15. The plungers are operated together through a rigid plate 39 to which operating thrust is applied, e.g. by the driver's foot, through a pad 36 of elastomeric material. The arrangement is such that pressure from the inlet ports acts on the plungers to urge them in the direction toward the pad and thereby establish " feel." As shown, the pad constitutes part of a sealing closure for the exhaust chamber. Annular grooves 22 in sleeves 18 communicate with the inlets and grooves 23 with exhaust. Control grooves 29 in the plungers communicate with chambers 21 in end plugs 19. In a modification a leaf spring (41), Fig. 3 (not shown), is interposed between the rigid plate and the plungers. The pad may be compressible a predetermined amount before any substantial thrust is exerted on the plungers.

Title: Improvements in and relating to devices for controlling the operations of washing machines
IPC: D06F39/00
Filed: 1960-01-21
Abstract: 949,549. Timer control of electric circuits. CONTROLS CO. OF AMERICA. Jan. 21, 1960 [March 16, 1959], No. 31927/63. Divided out of 949, 542. Heading G3T. A control device comprises a timer having timing control means for controlling selectable cycles of operation e.g. of a washing machine, a timing motor for driving said timing control means through the selected cycle at a slow speed, and a further motor for advancing said timing control means at a high speed to the desired starting position for the cycle and halting it automatically at that position. If, for example, a normally closed manually operable cycle preselection switch SM is opened, a momentary contact switch 102 is closed and a shaded pole motor 38 is energized through a printed circuit and a wiper brush 92 to drive the timer at a high speed and advance the brush 92 around the printed circuit in step by step manner. At the same time the solenoid action of the rotor of motor 38 throws rotor switch 82 over to contact 86 to establish a holding circuit shunting the switch 102 and breaking the circuit to the timer motor. After each step advance of brush 92 a cam 88 allows the opening of a search switch 55, which normally shunts the printed circuit, and motor 38 continues advancing brush 92 if the printed circuit is complete. When the brush reaches contact segment M in series with open switch SM then opening of search switch SS causes motor 38 to be de-energized as the circuit through motor coil 106 is broken. Rotor switch 82 then returns to its initial position and closes the circuit to the timer motor which then drives the timing control means at a slow speed through the cycle selected by actuation of switch SM. Specifications 949,547, 949,548 and 949,551 also are referred to.

Abstract: 230,941. Smallwood, A. Dec. 29, 1923. Gaseous-fuel furnaces.-In a tunnel furnace having a number of independently controllable heating-zones gas is supplied to each zone from a separate manifold i through a number of combustion shafts h, to each of which heated air is supplied in regulable quantities. The furnace shown has four heating - zones in addition to entrance and cooling sections, and on each side of each zone is a gas manifold i in dampered communication with a lower distributing-flue j supplied from a main k. From each manifold upcast passages or shafts h lead to the lower part of the tunnel, and into each passage a supply of air, regulatable by a damper at s<1>, is delivered from one or other of the flues n, m, n<1>, m<1>. The supplies of heating-gases through the shafts h may be controlled by dampers manipulated through openings h<1>. Preferably two pairs of independently controllable waste gas outlets are provided at the entrance end of the tunnel, and these lead to an underground flue p' adjacent which is the air inlet flue o. The air supply may also be heated in flues around the cooling- zone of the tunnel. The ports through which the heating-gases are delivered are so constructed that in the first of the heating-zones the gases flow more or less horizontally into the tunnel, as indicated at the left hand part of Fig. 5, and in the subsequent zones the direction of delivery approaches nearer to the vertical, as shown at the right.
